לֹ֧א יְבַקֵּ֛ר בֵּֽין־ט֥וֹב לָרַ֖ע וְלֹ֣א יְמִירֶ֑נּוּ וְאִם־הָמֵ֣ר יְמִירֶ֔נּוּ וְהָֽיָה־ה֧וּא וּתְמוּרָת֛וֹ יִֽהְיֶה־קֹ֖דֶשׁ לֹ֥א יִגָּאֵֽל׃
Ia tidak boleh memilah-milah antara yang baik dan yang buruk, dan ia tidak boleh menukarnya. Jika ia tetap menukarnya, maka hewan itu dan hewan penggantinya kedua-duanya akan menjadi kudus; hewan itu tidak dapat ditebus.
Sefer HaMitzvot
That is that He commanded us that the substitute [of a consecrated item] be consecrated. And in the explanation in Tractate Temurah (Temurah 4b), they said that His saying, "he shall not substitute for it," is a negative commandment that is rectified by a positive commandment. And it is also said there - in order to give a reason for the one who substitutes to get lashes, even though it is a negative commandment that is rectified by a positive commandment - and they said, "A positive commandment should not come and uproot two negative commandments." That is to say, this prohibition of substitution has been repeated twice - "He may not exchange or substitute it" (Leviticus 27:10) - but [only] one positive commandment appears; and that is, "it and its substitute shall both be holy" (Leviticus 27:33). Behold what we have wanted to explain has been explained. And the laws of this commandment have already been explained in Temurah - meaning when it stands and when it does not stand and what its law is. (See Bechukotai; Mishneh Torah, Substitution 1.)
Mishneh Torah, Positive Mitzvot
If a beast is exchanged for one that had been set apart as an offering, both become sacred, as it is said, “….it and the exchange thereof shall be holy” (Lev. 27:10).
Mishneh Torah, Negative Mitzvot
Not to transfer a beast set apart for sacrifice from one class of sacrifices to another, as it is said concerning the first-born of cattle, “(The firstling of the beasts….) no man shall sanctify it” (Lev. 27:26); that is, no one shall offer it up as another kind of sacrifice.
